Brief Summary:
The purpose of this study is to investigate whether reducing both the dose and the irradiated volume of cervical prophylactic irradiation in patients with nasopharyngeal cancer can maintain efficacy while decreasing toxicity. This will be achieved through a comparison of standard cervical prophylactic irradiation with a reduced-dose and reduced-volume approach.
Detailed Description:
Patients with non-metastatic nasopharyngeal cancer who are candidates for receiving definitive IMRT are randomly assigned to receive either standard cervical prophylactic irradiation or a reduced-dose and reduced-volume approach. The standard arm receives the conventional dose and volume of irradiation, while the experimental arm receives a lower dose and a smaller irradiated volume. Both groups will undergo intensity-modulated radiotherapy (IMRT) to the primary tumor and involved lymph nodes. The primary endpoint of this study is regional-control (RC), and secondary endpoints include overall survival (OS), local control (LC), distant metastasis-free survival (DMFS), and toxicity. All efficacy analyses will be conducted in the intention-to-treat population, and the safety population will include only patients who receive their randomly assigned treatment.
